RAILWAY-TIE.

SPECIFICATION forming'part of Letters -Patent No. 516,001, dated March6, 1894.

s am filed October 11, 1893.

To aZZ whom it may concern:

Be it known that I, JOSEPH DYSON, a citizen of the United States,residing-at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented certain new and useful ImprovenientsinRailway-Ties; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My invention relates to improvements in metallic railway ties; itsobject is to combine simplicity and economy of construction, greatdurability and security in use, and ease of ap plication; and itconsists in the construction, combination and arrangement of parts tosecure these ends as hereinafter fully described.

In the drawings Figure 1 is a plan view of my improved railway-tie withthe rails secured in place thereon. Fig.2 is a side view thereof, andFig. 3 an end view, both in elevation. Fig.4 is a top plan view of thetie detached. Fig. 5 is a side-view, and Fig. 6 an end View, of theholding clip, detached. Fig. 7 is a detached View of the locking-plate,and Fig. 8 a like view of thestuds or buttons for holding down therails. Fig. 9 is a partial elevation showing a modified structure of thetie, and Fig. 10 a like View showing a modification in form of theholding clip. Fig. 11 is a vertical longitudinal section in the centerline of the tie, showing all the parts in position.

A represents the rail, B the tie, O O holding clips, cl (1 studs orbuttons by which the rail is held to the tie, E E locking plates securedto the tie by bolt f and preventing lateral displacement of the rail,and g is a bolt securing the clip O to the tie. The tie B is preferablyof iron rolled in one piece and having a flat top and down-turnedflanges b b, as seen in Fig. 3. The holding clip 0 embraces the tie atits lower edges, being rudely of the shape of the letter W, as seen inFigs. 3 and 6, and is formed with the outer sides 0 c and the centralupward-curved portion 0', between which and the sides 0 the flanges b bof the tie snugly fit, which prevents any spreading apart of theflanges, being assisted by the bolt 9 which passes entirely through theclip and tie, and to receive which bolt the clip is provided with holesc corresponding with holes in the semi No. 487,804. (No model.)

tie. The sides 0 c of the holding clip are preferably formed withprojecting lugs 0 extending slightly above the tie and leaving betweenthem the notch 0 as wide as the flat base of the rail and even with thetop of the tie, as seen in Figs. 2 and 9. In this notch the rail restsand is prevented from moving sidewise. The rail is held down upon thetie by double-headed studs or buttons (1 d passing through the tie; toreceive which buttons the tie is perforated in that part covered by therail, with a hole b of a size to receive the head of the stud, fromwhich on each side extends a slot b long enough to admit the base of therail between the shanks of the studs when the latter are at the ends ofthe slots W, as shown by the dotted lines in Fig. 1. The enter one ofthe slots b viz., the one nearest the end of the tie, is extended,preferably but not necessarily from one side and in an angulardirection, far enough so that when the stud d in that slot is passed tothe end of such extension the base of the rail can be passed between thetwo studs and brought to a firm bearing on the tie. When this is donethe rail is forced against the inner stud, and, the outer stud beingbrought against the rail, the heads of the studs overlapping upon theflange or base of the rail prevent it from being lifted. plate E isplaced with its notch 6 against the shank of the outer stud, its edgeabutting a ainst the foot of the rail, and is secured to the tie by thebolt f passing through hole a The locking 1 and through a correspondinghole in the tie;

This looks everything in place and prevents any movement of the rail. Byremoving bolt f the outer stud can easily be moved into the extension 17of the slot 12 and leaves the rail free to, be lifted and replaced byanother in the shortest possible time. The removal of plate E will notleave the rail free to spread, as it will still be held by the lugs 0The upward curved central part c of the clip 0 bears against the underside of the studs d, and not only prevents them from dropping throughwhen inserted at the hole b, but keeps them protruding so far above thetie that the edge of the flange or base of the rail easily passes underthe head of the studs, as seen in 'Fig. 11.

The spreading of the track is well known to be one of the most fruitfulcauses of railway wrecks, and is caused by lateral movement outwardly ofone or both of the rails, there being of course no tendency to force therail inward toward the center line of the track. This outward actingforce is, of course, greatest on curves. It will be seen that in myimproved construction of tie the outward force acting on the rail isresisted by the stud d, the bolt f, and the lug c or bolt g, as well asby the friction of the clip 0 on the flanges of the tie. The boltsf andg and stud cl must all be sheared off before the rail can move, and asthe strain is distributed between a large number of ties, it isimpossible for enough to be concentrated on the bolts and stud to shearthem off and permit the rail to spread. As a further-means of resistancein localities where from any cause the rails are exposed to an unusualstrain, as on sharp curves, or where, as on bridges, &c., excessiveprecaution is to be observed, the tie may be so notched on the bottomedge of its flanges b b as to allow the clip O-to seat therein, theoutside of the clip being flush with the bottom of the flange b, as seenin Fig. 9, and thus the shearing strain is resisted, in addition to theother parts, by thesolid body of metal some inches in length in theflange of the tie. This last modification of structure will very seldomneed to be resorted to, and indeed, where the strain is not great, as onthe inside of curves, &c., the lugs 0 may be dispensed with and the clip0 formed. with a straight top edge, as seen in Fig. 10.

WhatIclaim as my invention, and desire to secure by Letters Patent, is

1. A metallic railway tie having a flat top anddepending flanges, incombination with double-headed holding studs seated in the top of thetie and a clip embracing both flanges of, the tie and secured thereto bya bolt passingthrough the clip and tie, substantially as described.

2. A metallic railway tie having a flat top and depending side flanges,in combination with double-l1eaded holding studs seated in a slotin thetop of the tie and a locking plate secured to the tie and having a notchto embrace the shank of the stud and prevent its moving in its slot,substantially as described.

3. A metallic railway tie having a flat top and depending flanges, incombination with double-headed holding studs seated in a slot in the topof the tie, a locking plate secured to the tie and having a notch toembrace the shank of the stud and prevent its moving in its slot, and aclip embracing both flanges of the tie and secured thereto by a'boltpassing through the clip and tie, substantially as described.

4.
